Ultra High Molecular Weight Polyethylene (UHMW/PE) | Spiratex

This specification provides for the identification of virgin, unmodified homopolymer ultra-high-molecular-weight polyethylene UHMW-PE molding and extrusion plastic materials in the form of powder, granules, or pellets. ISO provides a classification system based on various characteristics and a range of viscosity numbers determined in accordance with ISO The elongational stress is also be referred to as ZST and flow value, or both.

The values given in parentheses are for information only. The melt flow rate in accordance with test method D dd4020 be determined for this material because ultra high molecular weight polyethylene does not have a melt flow.

The elongational stress method is invalid on a previous thermally-processed material due to possible crosslinking.

This aetm is made in such a manner that the seller and purchaser can agree on the acceptability of different commercial lots or shipments. This specification is not intended to differentiate between various molecular weight grades of commercially available UHMW-PE, nor does it function to provide specific engineering d40200 for design purposes.

Work Item s – proposed revisions of this standard. This standard and ISO address the same subject matter, but differ in technical content.

It is advised that the user be familiar with Test Method D before attempting to use this test method. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Only Eq 1 listed in 3. ISO provides a classification system based on various characteristics and a range of viscosity numbers determined in accordance with ISO This standard does not purport to address all of the safety concerns, if any, associated with its use.

Note 1—This standard and ISO address the same subject matter, but differ in technical content. Application of this test method shall be limited to the characterization of virgin, unmodified UHMW-PE resins, not commercially processed products.

Sampled specimens shall be tested for dilute solution viscosity.
